glmFAB {FABInference}

FAB inference for generalized linear models

Description

asymptotic FAB p-values and confidence intervals for parameters in generalized linear regression models

Usage

glmFAB(cformula, FABvars, lformula = NULL, alpha = 0.05,
  silent = FALSE, ...)

Arguments

cformula

formua for the control variables

FABvars

matrix of regressors for which to make FAB p-values and CIs

lformula

formula for the lining model (just specify right-hand side)

alpha

error rate for CIs (1-alpha CIs will be constructed)

silent

show progress (TRUE) or not (FALSE)

...

additional arguments to be passed to glm

Value

an object of the class glmFAB which inherits from glm

Examples

# n observations, p FAB variables, q=2 control variables 

n<-100 ; p<-25 

# X is design matrix for params of interest
# beta is vector of true parameter values 
# v a variable in the linking model - used to share info across betas

v<-rnorm(p) ; beta<-(2 - 2*v + rnorm(p))/3 ; X<-matrix(rnorm(n*p),n,p)/8

# control coefficients and variables  
alpha1<-.5 ; alpha2<- -.5
w1<-rnorm(n)/8
w2<-rnorm(n)/8

# simulate data 
lp<-1 + alpha1*w1 + alpha2*w2 + X%*%beta 
y<-rpois(n,exp(lp))

# fit model
fit<-glmFAB(y~w1+w2,X,~v,family=poisson)
